The Incredible Machine
Everyone has a favorite attraction at an amusement park, and I am no different. However, unlike most people who seem to prefer rollercoasters, my favorite ride is a little more gentle. Every time I go to Coney Island, Navy Pier, or the Santa Monica Pier, I absolutely have to ride the Ferris wheel. The Ferris wheel is simple and yet also quite complex. That is, riding it is easy, but how it works is complicated. A series of carts are attached to a wheel, which is attached to a rim. That rim rotates vertically around an axis, and gravity keeps the carts upright. As simple as the ride seems, only advanced engineers can make safe and fun Ferris wheels.
What It Lacks in Thrills…
While the Ferris wheel is not as thrilling as a rollercoaster, it is still very exciting. The fact of being high in the air makes it so much more entertaining than a lot of rides. I mean, how often do you hang from that high up in daily life?
Nevertheless, I have to admit, I don’t seek Ferris wheels out because of their excitement. Rather, I find them very relaxing. At the top of the Ferris wheel, you get beautiful sights of the park. You also get a sense of calm that you don’t get in the hustle and bustle of the park below. Additionally, Ferris wheels are also gorgeous to look at when they are lit up at night. In fact, the original Ferris wheel was designed as much to be seen as to be ridden.
It Happened at the World’s Fair
The first Ferris wheel was made by and named after George Washington Gale Ferris, Jr. He designed it for the Chicago World’s Fair in 1893. It was the tallest attraction there, standing 264 feet high.
However, visitors to the fair were impressed by the size of the ride as well as the mechanics of it. In 1893, anything that was not turned by hand was considered a sight to see. And the wheel, which was a machine, was truly incredible to see. Further, as one visitor put it, the wheel was amazing because it seemed to be missing support. That is, it did not look like it could stand on its own. And yet it did and even rotated!
They Keep Reaching Higher and Higher
Ferris wheel technology has only improved since then. Most of today’s Ferris wheels are much larger than that first one. The largest in the world is the "Singapore Flyer," which stands slightly taller than twice what Ferris’s did! Today, the Ferris wheel is the most common amusement park ride. But that does not mean you should take them for granted. Instead, be thankful for Ferris’ invention. The next time you’re at an amusement park, don’t just look up at the impressive wheel in the sky on your way to a newer attraction.
Take it for a spin!

The cell cycle is a series of events in the life of a dividing eukaryotic cell. It consists of four stages: G1, S, G2, and M. The duration of the cell cycle varies from one species to another and from one cell type to another. The G1 phase varies the most. For example, embryonic cells can pass through the G1 phase so quickly that it hardly exists, whereas neurons are arrested in the cell cycle and do not divide.

Many scientific studies have found links between genius and mental illness, particularly bipolar disorder in which patients have violent mood swings between elation and depression. In one interesting Swedish study, 700,000 Swedes had intelligence tests at age 16 and again 10 years later. Those who scored well were four times more likely than the others to have developed bipolar disorder. The US neurologist James Fallon came up with a convincing argument based on his own findings in the field: the brain area involved in mood swings is the same area where creativity is born. This may explain why some people can draw previously unseen connections among ideas, images, shapes and the like.

It is widely accepted that eating sugar can cause weight gain. Indeed, many people who are susceptible to weight gain report that, in their own experience, eating large amounts of sugar is invariably followed by a measurable weight gain within a few days. However, it is likely that common wisdom has confused cause and effect.

Recent studies suggest that hormonal changes associated with stress can cause weight gain, and there is ample evidence that people who are fond of sugar tend to eat more of it when they are under stress.

The argument employs which one of the following argumentative strategies?

India’s baffling array of state and national labor laws date to the 1940s: one provides for the type and number of spittoons in a factory. Another says an enterprise with more than 100 workers needs government permission to scale back or close. Many Indian businesses stay small in order to remain beyond the reach of the laws. Big firms use temporary workers to avoid them. Less than 15% of Indian workers have legal job security. The new government can sidestep the difficult politics of curbing privileges by establishing a new, simpler labor contract that gives basic protection to workers but makes lay-offs less costly to firms. It would apply only to new hires; the small proportion of existing workers with gold-star protections would keep them.

Antidiuretic hormone (ADH) is important in maintaining homeostasis in mammals. ADH is released from the hypothalamus in response to high tissue osmolarity. In response to ADH, the collecting duct and distal tubule in the kidney become more permeable to water, which increases water reabsorption into the capillaries. The amount of hormone released is controlled by a negative feedback loop.

Based on the model presented, which of the following statements expresses the proper relationship between osmolarity, ADH release, and urine production?

Platelets are fragments oflarger celis and normaliy circulate in the blood without adhering to blood vessel walls.
